Gorgeous color and clarity in good light - a bit noisy at higher ISOs. I like the fact that I can quickly adjust exposure compensation with an icon on the left side of the camera screen. I posted the full-sized cropped image - to get a better view of its quality, look at it at "large" size here.

OK, I'm a believer! Brenda and I got one of the new Verizon family plans, so we all now have data capability. Going to have to finally trade in my 6-year-old Samsung 990A for a new phone in September (when I'm eligible for a new phone at reduced cost). I've been reading about the Galaxy S3 and your photos certainly look great!
